She died of cardiac arrest on October 25 at Hoag Hospital in Newport Beach, according to her brother, Scott Mounts.

She had been in a drug-induced coma since October 20, when she first went into cardiac arrest following a workout at her gym, her brother said. 'She was a vegetarian, didn’t drink, didn’t smoke and worked out religiously', he said Tuesday in a telephone interview.

A chartered alternative investment analyst, Mounts founded MAP Alternative Asset Management in 2006 following jobs in New York at Goldman Sachs and Morgan Stanley, where she specialized in fixed-income derivatives.

MAP, with fewer than 10 employees, is an investment adviser with input on more than $35bn in client assets, specializing in managing risk in fixed-income portfolios, according to Marco Ricciardulli, a senior consultant. Clients include large public and corporate pensions. A planned fixed-income fund of hedge funds, with a focus on emerging managers, has yet to open, Ricciardulli said.
